How can I enable only the left most Highcharts XAxis plot line on DateTime Line chart. I suppose there should be a default option to display XAxis line without needing to know the minimum/start value
My progress so far -> https://jsfiddle.net/Lpjb9wc7/
const chart = Highcharts.chart('container', { credits: { enabled: false, }, title: null, xAxis: { title: 'Session', type: 'datetime', tickInterval: 3600 * 1000, gridLineWidth: 1 }, yAxis: { gridLineWidth: 0, title: { text: 'Temperature', }, }, legend: { enabled: false, }, plotOptions: { series: { marker: { enabled: false, }, }, }, series: [ { data: [ [1369206795000, 1], [1369225421000, 3], [1369230934000, 2], ], }, ],
});

Answer
You need to change the dafault value of the lineWidth
property.
yAxis: { lineWidth: 1, ... }
